Unique plan to generate energy from elevators in buildings
Vienna: Scientists have come up with a new idea for energy storage that will transform high-rise buildings into large batteries, an innovation that could help improve energy quality in urban areas.
According to a foreign news agency, in a study published a few days ago in the journal Energy, scientists have come up with a rare idea based on gravity, in which the elevation of tall buildings and vertical height can be used to store energy. Is.
This idea, called Lift Energy Storage Technology (Lest), stores energy by lifting wet sand containers or other high-density objects.
Scientists say the technology combines two storage spaces, one at the bottom of the building and the other at the top of the same building.
When elevators installed in buildings go up from the bottom, energy is stored in them as hidden energy due to rising above the storage container.
In the proposed scenario, when the energy demand in the building was low, the robots loaded heavily into the elevator and stored the energy in the upper part of the building.
The researchers said that the process of loading or unloading the containers in the elevator was carried out by an automatic trailer which used to remove the containers from the storage space built up or down. That is, the trailer would enter the elevator, go up or down, exit the elevator, and place the container in the storage area.
When the demand for energy increases, the weight is put back in the elevator and sent down to make more energy.
According to researchers at the International Institute for Applied Systems Analysis, since the elevators are already installed in the buildings, the project will not require any additional investment or allocation of space.
Researchers estimate that there are approximately 18 million elevators in operation worldwide, a large number of which are used without work.
Since the amount of energy stored depends on the height of the building, researchers estimate that a building like the Burj Khalifa could potentially store energy from 9 megawatts to 90 megawatts.
Researchers estimate that the combined use of this technology in all the tallest buildings in the United States could possibly range from 6.5 gigawatt-hours to 65 gigawatt-hours, and in China from approximately 7.3 gigawatt-hours to 73 gigawatt-hours. Energy can be stored up to
